FLAGSTAFF.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed March 28, 1914. Serial No. 827,856.

To all whom it may concern:

Be it known that I, ELMER E. CARR, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Flagstaffs, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to flag staffs and has for its object to provide a staff which may be firmly supported in upright position while still permitting it to be turned to a horizontal position, either for use or for providing a ready means of access to the upper portions of the staff for painting or repairing the same.

The invention is exemplified in the structure to be hereinafter described and which is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation showing the staff in horizontal position with a detail of the building to which the staff is applied shown in cross section; Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is an end elevation showing the stafi in upright position and with some of the parts shown in cross section, Fig. 4 is a detail sectional view showing a modified form of construction and Fig. 5 shows in elevation, a detail of the form of construction illustrated in Fig. 4'.-

ln carrying out the invention a pair of mating plates 10 and 11 are desirably pro- Vided to form a socket for receiving the lower end, as 12, of the staff 13. In the form of construction illustrated in Figs. 1, 2 and 3, the lower end 12 of the staff 13 is made of square cross section. In this instance the upper portions of the socket plates 10 and 11 have flat inner faces, as 14:, for engagement with the two sides of the staff, inturned marginal flanges, as 15, for embracing the edges of the staff, and instanding transverse shoulders, as 16, for en gagement with the lower end of the staff. The plates are secured together and firmly clamped upon the staff for securing the same in place. Preferably a plurality of clamping bolts, as 17, are provided for this purpose. As shown these bolts are arranged in pairs upon opposite sides of the staff and each bolt extends through apertured lugs, as 18, 19, provided upon the plates 10 and 11, respectively.

In order that the two socket plates 10 and 11 may be cast from a single pattern they are desirably of like construction. In addition to the features already described each plate is provided with a trunnion socket 20 and with an instanding spacing lug 21, the latter being located below the transverse shoulder 16 and the lugs 21 and the two plates being of such length as to meet when the plates are clamped upon the lower end 12 of the staff. Counter weights, as 22, 23 are secured to the plates 10 and 11 adjacent their lower ends.

Trunnions, as 2%, for entering the sockets 20 of the plates 10 are desirably mounted in standards, as 25 and 26. These standards are secured to the structure of the building to which the flag staff is to be applied, as by being bolted to the I-beams 27 and 28, respectively, of a roof. Usually the standards 25 and 26 will be so located with reference to the coping, as 29, of the roof that when the staff 13 is turned to a horizontal position in one direction it will rest upon the coping and project over the side of the building. If desired, a chair, as 30, Fig. 2, may be mounted on the coping to receive the staff. When such a chair is used a pin 31 adapted to be thrust through the arms of the chair above the staff will preferably be provided for securing the staff in the horizontal position. The standards 25, 26 will also be spaced apart from the coping 29 a sufficient distance to permit the coping to be secured by the counter weights 22, 23 when the staflf is turned to a horizontal position in the other direction. The turning of the staff to this last mentioned position will serve to provide convenient access to the staff throughout its entire length for the purpose of painting or repairing the same. The invention thereby serves to reduce the expense of maintaining the staff in proper repair by avoiding the expense attendant upon the employment of a skilled artisan to mount the staff for the purpose of painting those portions which would be otherwise out of reach.

The staff 13 will commonly be used in the upright position illustrated in Fig. 3. Provision is accordingly provided for firmly securing it in this position. To this end a pin 32 is removably set through the standards 25, 26, and through the plates 10 and 11 and provision is desirably made for yieldingly drawing the standards 25, 26 together to clamp the plates 10 and 11 in an upright position between them. As shown, a wedge shaped key 33 is set through the pin 32 adjacent one end of the same in such a position as to engage the corresponding standards 25 when inserted. Forcing the key 33 in place accordingly serves to draw the standards 25, 26 firmly together for clamping the plates 10 and 11 between them. WVhen the staff 13 is to be turned to a horizontal position in either direction the key 33 is removed and the pin 32 withdrawn. In some instances a staff 34 having a cross sectional form of a cross'with equal arms is employed. This form of construction is illustrated in Fig. 4. When such a staff is used, plates 35, 36, similar to the plates 10 and 11, but having grooves, as 37 and 38 for receiving the opposite sides of the staff are employed. To insure that the staff socket will be gripped between the standards 25, 26, at more than one point when the key 33 has been thrust into position, lugs, as 39 and 40 are formed upon the plates 10 and 11, re spectively, for engagement with the corresponding standards 25,26, below the level of the pin 32. Most desirably these lugs are located in substantial alinement with the instanding lugs 21.

In the form of construction shown no mechanism is provided for turning the staff 13 upon the trunnions 24. It will be understood, however, that this embodiment of the invention has been chosen for the purpose of the disclosure contained herein merely to promote simplicity of illustration.

I claim as my invention 1. In combination, a pair of inwardly yielding standards, a flag staff pivotally mounted upon the standards to swing between them, and means for compressing the standards upon the staff.

2. In combination, a pair of inwardly yielding standards, a flag staff pivotally mounted upon the standards to swing between them, a pin removably passed through both of the standards and the stafl at a point which is spaced apart from the axis of pivotal movement of the staff and means applied to the pin for drawing the standard; together to compress them upon the sta r 3. In combination, a standard, a flag stan' pivotally mounted thereon to swing by the standard, a pin removably passed through the standard and staff at a point which is spaced apart from the axis of pivotal movement of the staff when the staff and standard are in alinement'and means applied to the pin for pressing the staff and standard together. 7

4. In combination, a flag staff of crossshape in section, and a socket therefor comprising a pair of plates each having flat surfaces for engaging the adjacent faces of two opposing arms of'the cross and a longitudinal groove for receiving the intermediate arm and means for binding the plates together.

5. A tilting flag staff comprising, in combination, a pair of inwardly facing longitudinally grooved plates spaced apart throughout substantially the whole of their length and forming a socket to receive the CHARLns B. GILLSON, E. M. KLATCHER.
